
Water is Florida’s most valued resource

Florida’s #1 concern is water conservation & quality

The past 20 years, surface waters in Florida have
become very sensitive to small additions of
pollutants

Caused widespread ecosystem changes in estuaries,
lakes, rivers & the Everglades
Population growth increases water needs,
storm water runoff & nonpoint source pollution
1990: 12.9 Mil 2015: 19.9 Mil 2030: 30 Mil ??
Population Rank –
rd
3 in U.S. behind California &Texas
Florida will need 26% more water – 9.1 billion
gallons of fresh water every day
Current Issues:
Water supply needs already exceed capacity in some areas
Water accessibility
Competition between urban, agricultural & recreational uses
Costs of mitigation
Nutrients in Florida Waters
Phosphorous (P) & nitrogen
(N) are naturally occurring
Plants require nitrogen &
phosphorous to grow
If in short supply in water
plant growth is limited
In FLORIDA, waters are
naturally productive, why?

Provide habitat for wildlife:

Waterfowl

Nesting birds

Attract fish

Excellent fisheries

Recreational opportunities
Nutrients in Florida Waters
Florida waters are naturally
productive:
P deposits in underlying soil
P & N fertilizer application runoff
High nutrient levels in water
results in high growth of aquatic
plants, especially algae & floating
plants
Can be a problem if aquatic
plants interfere with intended use
of water body
Why Manage Aquatic Plants
Non-native plant problems
Nonnative plants out-compete
native plants:
Form monocultures
Interfere with wildlife that
depends on native plants
Obstruct water flow
Hinder navigation
Reduce recreation uses
Destroy aesthetics
